Based on these data alone, identify the most appropriate hypothesis that explains the effect of peptides 1 and 2 on the quorum-sensing pathways of s. aureus.

Data shows results of an experiment which was added to each peptide to culture the TRAP. Mutants of S. aureus and culture of the Agr. mutant of s. aureus.
Peptide 1 and three blocks Agr pathway
Peptide 2 blocks TRAP pathway
This is because the mutants are already blocked for one of the pathways.
Therefore it gives way to determine which pathway each peptide act on.

Iwould say silver and gold
